> Extend StreamingFileSink BulkFormats to support arbitrary roll policy's
> ------------------------------------------------------------------------
>
> Key: FLINK-11499
> URL: https://issues.apache.org/jira/browse/FLINK-11499
> Project: Flink
> Issue Type: Improvement
> Components: filesystem-connector, Streaming Connectors
> Reporter: Seth Wiesman
> Priority: Minor
>
> Currently when using the StreamingFilleSink Bulk-encoding formats can only be
> combined with the `OnCheckpointRollingPolicy`, which rolls the in-progress
> part file on every checkpoint.
> However, many bulk formats such as parquet are most efficient when written as
> large files; this is not possible when frequent checkpointing is enabled.
> Currently the only work-around is to have long checkpoint intervals which is
> not ideal.
>
> The StreamingFileSink should be enhanced to support arbitrary roll policy's
> so users may write large bulk files while retaining frequent checkpoints.
